Pointer Authentication is enabled for Non-secure world irrespective of the value of these build flags if the CPU supports it. The patch also fixes the description of fiptool 'help' command.

2019-02-27	b86048c Browse files » Add support for pointer authentication ... The previous commit added the infrastructure to load and save ARMv8.3-PAuth registers during Non-secure <-> Secure world switches, but didn't actually enable pointer authentication in the firmware. This patch adds the functionality needed for platforms to provide authentication keys for the firmware, and a new option (ENABLE_PAUTH) to enable pointer authentication in the firmware itself. This option is disabled by default, and it requires CTX_INCLUDE_PAUTH_REGS to be enabled.

2019-02-27	5283962 Browse files » Add ARMv8.3-PAuth registers to CPU context ... ARMv8.3-PAuth adds functionality that supports address authentication of the contents of a register before that register is used as the target of an indirect branch, or as a load. This feature is supported only in AArch64 state. This feature is mandatory in ARMv8.3 implementations. This feature adds several registers to EL1. A new option called CTX_INCLUDE_PAUTH_REGS has been added to select if the TF needs to save them during Non-secure <-> Secure world switches. This option must be enabled if the hardware has the registers or the values will be leaked during world switches. To prevent leaks, this patch also disables pointer authentication in the Secure world if CTX_INCLUDE_PAUTH_REGS is 0. Any attempt to use it will be trapped in EL3.

The memory descriptors describing the list of executable images are created in BL2 R/W memory, which could be possibly corrupted later on by BL31/BL32 due to overlay. This patch creates a reserved location in SRAM for these descriptors and are copied over by BL2 before handing over to next BL image. Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR is enabled.

2018-10-16	3ff4aaa Browse files » AArch64: Enable lower ELs to use pointer authentication ... Pointer authentication is an Armv8.3 feature that introduces instructions that can be used to authenticate and verify pointers. Pointer authentication instructions are allowed to be accessed from all ELs but only when EL3 explicitly allows for it; otherwise, their usage will trap to EL3. Since EL3 doesn't have trap handling in place, this patch unconditionally disables all related traps to EL3 to avoid potential misconfiguration leading to an unhandled EL3 exception.
